AI Technical Summary

Benefits of technology

The present invention provides an inkjet recording method for recording images using two ink compositions. The inkjet recording medium has a porous layer that contains inorganic microparticles and a water-soluble resin. The porosity of the layer is at least 50% and the ink compositions have a maximum total ejection amount that is less than 90% of the absorption capacity of diethylene glycol. The recorded article comprises the inkjet recording medium with the porous layer. The technical effects include improved image quality and reduced bleeding.

Problems solved by technology

However, in the case of printing at a high speed or printing of a large number of sheets, it may be difficult to ignore the influence of a humidity environment or drying conditions after recording on image quality.
For example, a color difference is generated between stacked portions and non-stacked portions of recorded articles that are stacked as sheets, whereby color tones become different between images or within an image, resulting in stack irregularities in some cases.

-Preparation of Water-Impermeable Support-

[0171]50 parts of LBKP obtained from acacia and 50 parts of LBKP obtained from aspen were respectively processed by beating using a disc refiner to obtain a Canadian freeness of 300 mL, and thus a pulp slurry was prepared.

[0172]Subsequently, to the pulp slurry obtained as described above were added 1.3% of cationic starch (trade name: CAT 0304L, manufactured by Nippon NSC, Ltd.), 0.15% of anionic polyacrylamide (trade name: DA4104, manufactured by Seiko PMC Corp.), 0.29% of an alkyl ketene dimer (trade name: SIZEPINE K, manufactured by Arakawa Chemical Industries, Ltd.), 0.29% of epoxidated behenic acid amide, and 0.32% of polyamide-polyamine-epichlorohydrin (trade name: ARAFIX 100, manufactured by Arakawa Chemical Industries, Ltd.), based on the pulp, and thereafter 0.12% of an antifoaming agent was added thereto.

[0173]The pulp slurry prepared as described above was made into paper using a Fourdrinier paper machine. In a process of drying ...

example 2

[0252]An ink-receiving layer was formed in a manner substantially similar to that in Example 1 except that, in Example 1, a coating amount of an ink-receiving layer coating solution was changed from 150 g / m2 to 175 g / m2, and an in-line solution was in-line mixed by changing a velocity (coating amount) of the in-line solution from 10 g / m2 to 11.7 g / m2, followed by coating on a water-impermeable support, and thereby an inkjet recording paper was obtained. A thickness of the ink-receiving layer, the DEG absorption capacity and porosity thereof are as shown in Table 1 shown below. Furthermore, evaluations similar to those in Example 1 were performed.

example 3

[0253]An ink-receiving layer was formed in a manner substantially similar to that in Example 2 except that, in Example 2, an amount of the (6) polyvinyl alcohol solution in “Composition of Ink Receiving Layer Coating Solution” was changed from 26.0 parts by weight to 36.4 parts by weight, and thereby an inkjet recording paper was obtained. A thickness of the ink-receiving layer, the DEG absorption capacity and porosity thereof are as shown in Table 1 shown below. Furthermore, evaluations substantially the same as Example 1 were performed.

Abstract

An image is recorded by ejecting two or more ink compositions on a porous layer that contains inorganic microparticles and a water-soluble resin and has a porosity [%] of 50% or more with a maximum total ejection amount (mL / m2) set at less than 90% of an absorption capacity (mL / m2) of diethylene glycol in the porous layer. The porosity=(absorption capacity of diethylene glycol (mL / m2)) / (thickness of porous layer (μm))×100. The maximum total ejection amount=(maximum ejection amount of one dot (mL / m2))×(total amount of ink (%)). An inkjet recording method capable of inhibiting color change from occurring to cause color irregularities when papers are stacked on an image portion within a relatively short time after recording in high-speed processing or processing of a large number of sheets, and capable of stably obtaining images recorded with desired color tone.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 USC 119 from Japanese Patent Application No. 2009-34609 filed on Feb. 17, 2009 and Japanese Patent Application No. 2009-237567 filed on Oct. 14, 2009, the disclosures of which are incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an inkjet recording method, wherein an inkjet method is used to eject an ink to carry out recording, and a recorded article using the same.[0004]2. Description of the Related Art[0005]As an image recording method for recording color images, various methods have been proposed in recent years. In all of these methods, qualities of recorded articles such as image quality, tone and reduced curling after recording are highly required.[0006]For example, an inkjet recording method using an inkjet recording medium, which has an ink-receiving recording layer formed to have a porous structure has been pr...
